Operation
4. Test / enable / disable switch (cont.)
- Test position — The test switch provides a quick diagnostic
status of the audible alarm, alarm status indicator and remote
alarm contacts. When pressed, the audible alarm will sound,
the alarm lamp will illuminate, and the remote contacts will
change state. The "test" position is momentary. Once pressed,
the switch will automatically reset to the enable position
upon release.

Maintenance
ABB does not provide a specific schedule for preventative
maintenance as conditions will vary based on location and
the environmental factors presented at each installation site.
However, periodic inspections should be scheduled to verify
that the SPD does not indicate a failure mode. Inspections
should also be made to check the integrity of the electrical
supply connections to the SPD to ensure continued reliable
performance.
The unit's heavy-duty construction is designed to provide
years of uninterrupted service.
The unit contains no serviceable parts.
L'unité ne contient aucune pièce réparable.
NOTICE
In the event of an SPD alarm condition, do not attempt to
dis-assemble the SPD to replace fusing or other components.
The SPD contains thermally protected MOVs that will only open
when the SPD has failed in a non-serviceable condition. The
entire SPD must be replaced.
En cas de condition d'alarme du SPD, n'essayez pas de démonter
le SPD pour remplacer les fusibles ou d'autres composants. Le
SPD contient des MOV protégés thermiquement qui ne s'ouvrent
que lorsque le SPD tombe en panne et ne fonctionne plus.
L'ensemble du SPD doit être remplacé.

5. Surge counter LCD
The surge counter will sense and record transient surge events
that have been mitigated by the SPD. The counter has been
designed to detect transients that exceed the peak sine wave
by more than 70%. If desired, the surge counter display can be
reset to zero at any time by pressing the reset button located
on the LCD display.

Servicing/troubleshooting
Should a condition occur that results in premature failure of
the SPD, the integral SPD suppression thermal fusing will safely
interrupt current flow through the SPD without disrupting power
to the protected equipment. This will remove the SPD from the
power system, and the load equipment will remain unprotected
from subsequent surge activity until the SPD is replaced.
If a change in operational status/alarm indication occurs, a
qualified (licensed) electrician should inspect the electrical
system to verify electrical system integrity. If the SPD remains
in alarm after inspection/corrections have been made, the SPD
should be replaced.
